SPRlNG-BED..

SPECIFICATION forming part of Letters Patent No. 475,763, dated May 31,1892. Application filed January 20, 1892. serial No. 418,681. (Nomodel.)

To aZZ whom it may concern.-

Be itknown that I, LoUIs ADOLPHE FRIGON,

a citizen of France, having legally declaredmy intention of becoming acitizen of the United States, residing at Baltimore, in the State ofMaryland, have invented certain new and useful Improvements in SpringBeds, Couches, or Lounges; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appcrtains to make and use thesame.

My invention relates to portable springbeds for invalids and for otherpurposes; and the same consists in certain novel constructions,combinations, andarrangcments of the parts of such beds whereby greatdurability, lightness, elasticity, ready means of adjustment, andsecurity against casual change in such adjustment are secured, as willhe hereafter described and specifically claimed.

In the accompanying drawings, Figure 1 is a perspective View of myimproved springbed with its head-rest adjusted at an angle; Fig. 2, avertical longitudinal section of the same, in this view the dotted linesindicating a change in the angle of the adjustment of the head-rest; andFig. 3 is a rear end view of the spring-bed as adjusted in the otherfigures.

A in the accompanying drawings indicates the horizontal portion of thespringbed proper, and B the adjustable head-rest portion of the same.

C is a portable skeleton supporting-frame composed of longitudinalstrips a and transverse strips a', the latter extending laterally somedistance beyond the outermost longitudinal strips and also occupyingpositions some distance inward from the front and rear ends of saidstrips, as represented.

D are ordinary bed-springs applied between the bed proper A and theframe 0, being secured to the sacking or ticking material G of the bedproper and to the slats or strips a, as represented.

E are pendent ratchet-toothed curved bars pivoted to brackets c on theback of the headrest portion B. The teeth d of these bars form adjustingstop-notches cl, which catch upon open loops F, applied to the rear endsof the outermost longitudinal strips a, there being one loop in each ofsaid strips, as shown. By means of the said toothed bars the headportion 13 can be set at greater or less angle to the portion A, asoccasion requires, and this adjustment is very conveniently effected byswinging the bars backward out of looking connection with the open loopsF and allowing the head-rest, with the bars, to descend the distance ofthe length of a ratchettooth notch and then swinging the bars forward orallowing them to swing forward by their gravity, so as to form alockingconnection with the loops. The adjustment just described effectsthe lowering of the headrest; but should it be desired to raise thehead-rest the bars are swung backward and raised the distance of thelength of a ratchettooth notch and allowed to swing forward, so as toform a lockin g connection with theloops. The two adjustments justdescribed are illustrated in Fig. 2, the dotted lines indicating thelower position and the full black lines 21: indicating the higherposition. At the lower ends of the bars pins f are inserted to preventthe bars being raised entirely out of connection with the loops. Themeans for effecting these adjustments and controlling the adjustmentand, also, the special construction of the bed proper and the head-restportion thereof I will now describe.

The bed proper consists of a skeleton frame formed of wooden bars g,united atiheir ends by scarfed or lapping joints g. The headrest isformed of similar bars 9 united at their ends by similar joints g and tothe top and bottom of both of these frames strong ticking or sackingmaterial G G is tacked, as illustrated in Fig. 1 and also in the otherfigures.

At the junction of the head-rest portion with the bed proper a slightspace It is left between the frame-pieces of the respective portions ofthe bed, in order that a flexible joint m shall be formed between thehead-rest and the bed proper by means of the ticking material, and atthis joint the upper and lower pieces of ticking material are stitchedtogether near each side of the bed, as illustrated at n. By thisconstruction a ver enduring wooden edge is secured all around the bedproper and head-rest portion, there only being a slight separation atthe place h,where thejoint is formed on each side, and means areafforded by the wooden frame-bars of both the bed proper and thehead-rest portion for securely tacking and stretching the tickingmaterial of the bed proper and headrest.

In the drawings a filling H H is represented as applied between theticking material, and while this is preferable such filling, of eitherhair or cotton, may be dispensed with. It may be also practicable toleave out all of the lower ticking material, except that which forms thejoint at m, and to attach the springs to the portion H; but it is farpreferable to construct the bed as repre sented.

To each of the side bars having ratchetteeth, a cord I is connected, andthese cords are carried up to staples p on the back of the head-rest andpassed through said staples and through holes p in the head-rest andunited to a tasselp at the center of the front of the head-rest.

To the rear end of the portable supportingframe 0 a perforatedadjusting-strap J is fastened and carried up over the top of thehead-rest portion and temporarily secured to a button q, secured in theupper frame-bar of the head-rest portion, as shown. 3y means of thecords and this perforated strap a person lying upon the bed or the nursecan, by pulling the tassel and unbuttoning the strap, disconnect theratchet-toothed bars from the locking-loops F and lower the head-rest,and by allowing the bars to swing forward to locking positions with theloops effect the desired adjustment and also retain said adjustment bybuttoning the strap J through another of its adjusting-holes to thebutton q. This operation would lower the head-rest. To raise thehead-rest, it is only necessary to move the bars backward, (afterunbuttoning the strap and raising them and the head-rest.) and then toallow the bars to swing forward to their locking position with the loopsand then to rebutton the strap by means of a properly-located hole.

The within-d escribed spring-bed is adapted to be set within a bedsteadand supported by the inner ledges thereof in the same manner as anordinary spring-bed frame. If such manner of use is not desired, theskeleton frame 0 might be provided with supportingstandards or appliedin a lounge-frame in any suitable manner, so as to be capable of movingup and down on its springs and of having its head-rest adjusted atdifferent angles, as described and illustrated.

For insuring a parallel up-and-down movement of the bed proper andlimiting its upward movement under the influence 0f the springs flexiblestraps s are provided, said straps yielding with the springs to adownward Weight.

NVhat I claim as my invention is 1. Thecombination ofthesupporting-frame, the frames of the bed proper and head-rest, tickingmaterial applied to the last-mentioned frames, so as to form thereof thejoint between the head-rest and bed proper, springs arranged upon thesupporting-frame and connected to the bed proper, limitation-strapsattach ed to the supporting-frameand bed proper, and suitable adjustablesupports attached to the supporting-frame and the head-rest,substantially as described.

2. The combination of thesupporting-frame, the frames of the bed properand head-rest, ticking material applied to the last-mentioned frames, soas to form thereof the joint between the head-rest and bed proper,springs arranged upon the supporting-frame and connected to the bedproper, the pendent pivoted ratchet-toothed bars attached to theheadrest, the open loops attached to the supporting-frame, the cordsconnected to the ratchettoothed bars and passed through the head restand united at the center thereof, and the perforated retainingstrapattached to the supporting-frame, and the button for said strap attachedto the head-rest, substantially as described.

In a spring-bed, the combination of the bed proper, the adjustablehead-rest jointed to said bed proper, the supporting frame, springs onsaid frame and connected to the said bed proper, the pendent pivotedratchettoothed bars attached to the head-rest, the open loops attachedto the sides of the supporting-frame, and the springs arranged on saidframe between it and the bed proper, substantially as described.

In testimony whereofI hereunto aifix my signature in presence of twowitnesses.

LOUIS ADOLPI-IE FRIGON.
